2004.01.23 04:48 "How to convert MINISBLACK to PHOTOMETRIC_RGB", by Pushkar Pradhan
When I create a subset image (to take only 3 bands out of 6) IMAGINE software creates a MINISBLACK TIF file (there seems to be no option to change this). This is what tiffinfo reports: TIFFReadDirectory: Warning, data/ms-denver.tif: unknown field with tag 33550 (0x830e) encountered. TIFFReadDirectory: Warning, data/ms-denver.tif: unknown field with tag 33922 (0x8482) encountered. TIFFReadDirectory: Warning, data/ms-denver.tif: unknown field with tag 34735 (0x87af) encountered. TIFFReadDirectory: Warning, data/ms-denver.tif: unknown field with tag 34737 (0x87b1) encountered. TIFF Directory at offset 0xcd6a Image Width: 138 Image Length: 127 Resolution: 1, 1 (unitless) Bits/Sample: 8 Sample Format: unsigned integer Compression Scheme: None Photometric Interpretation: min-is-black Extra Samples: 2<unspecified, unspecified> Orientation: row 0 top, col 0 lhs Samples/Pixel: 3 Rows/Strip: 59 Planar Configuration: single image plane Software: IMAGINE TIFF Support Copyright 1991 - 1999 by ERDAS, Inc. All Rights Reserved @(#)$RCSfile: etif.c $ $Revision: 1.9.2.2 $ $Date: 2002/01/14 13:57:53EST $ Now I want to read this file in MATLAB whose TIFF reader is limited to reading RGB and PALETTED images (that too only 8-bit and 16-bit). Thus it only reads the 1st band of this file. I saw there is utility pal2rgb but is there something similar to min-is-black images to RGB interpretation? Thanks, Pushkar Pradhan
